SECTION 12.2. INDEMNIFICATION. BORROWER HEREBY INDEMNIFIES LENDER AND EACH AFFILIATE THEREOF AND THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, ATTORNEYS AND AGENTS FROM, AND HOLDS EACH OF THEM HARMLESS AGAINST, ANY AND ALL LOSSES, LIABILITIES, CLAIMS, DAMAGES, PENALTIES, JUDGMENTS, DISBURSEMENTS, COSTS AND EXPENSES (INCLUDING REASONABLE ATTORNEYS’ FEES) (COLLECTIVELY, “CLAIMS”) TO WHICH ANY OF THEM MAY BECOME SUBJECT WHICH DIRECTLY OR INDIRECTLY ARISE FROM OR RELATE TO (A) THE NEGOTIATION, EXECUTION, DELIVERY, PERFORMANCE, ADMINISTRATION OR ENFORCEMENT OF ANY OF THE LOAN DOCUMENTS, (B) ANY OF THE TRANSACTIONS CONTEMPLATED BY THE LOAN DOCUMENTS, (C) ANY BREACH BY BORROWER OF ANY REPRESENTATION, WARRANTY, COVENANT OR OTHER AGREEMENT CONTAINED IN ANY OF THE LOAN DOCUMENTS, (D) THE PRESENCE, RELEASE, THREATENED RELEASE, DISPOSAL, REMOVAL OR CLEANUP OF ANY HAZARDOUS SUBSTANCE LOCATED ON, ABOUT, WITHIN OR AFFECTING ANY OF THE PROPERTIES OR ASSETS OF BORROWER OR ANY SUBSIDIARY, (E) ANY ACT OR OMISSION OF LENDER BASED UPON ANY FAX OR ELECTRONIC TRANSMISSION OR (F) ANY MATTER RELATED TO ANY LETTER OF CREDIT, INCLUDING, WITH RESPECT TO ALL OF THE ABOVE, ANY CLAIM WHICH ARISES AS A RESULT OF THE NEGLIGENCE OF LENDER; PROVIDED, HOWEVER, THAT BORROWER’S INDEMNIFICATION OBLIGATIONS UNDER THIS SECTION 12.2 SHALL NOT APPLY TO THE EXTENT THAT THE CLAIMS ARISE AS A RESULT OF THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF ANY INDEMNIFIED PERSON.

Section 12.3. Limitation of Liability. Neither Lender nor any Affiliate, officer, director, employee, attorney or agent of Lender shall have any liability with respect to, and Borrower hereby waives, releases and agrees not to xxx any of them upon, any claim for any special, indirect, incidental, exemplary, punitive or consequential damages suffered or incurred by Borrower in connection with, arising out of, or in any way related to, this Agreement or any of the other Loan Documents, or any of the transactions contemplated by this Agreement or any of the other Loan Documents.

Section 12.4. No Waiver; Cumulative Remedies. No failure on the part of Lender to exercise and no delay in exercising, and no course of dealing with respect to, any right, power or privilege under this Agreement shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege under this Agreement preclude any other or further exercise thereof or the exercise

of any other right, power or privilege. The rights and remedies provided for in this Agreement and the other Loan Documents are cumulative and not exclusive of any rights and remedies provided by law.

Section 12.5. Successors and Assigns. This Agreement is binding upon and shall inure to the benefit of Lender and Borrower and their respective successors and assigns, except that Borrower may not assign or transfer any of its rights or obligations under this Agreement without prior written consent of Lender.

Section 12.6. Survival. All representations and warranties made in this Agreement or any other Loan Document or in any document, statement or certificate furnished in connection with this Agreement shall survive the execution and delivery of this Agreement and the other Loan Documents, and no investigation by Lender or any closing shall affect the representations and warranties or the right of Lender to rely upon them.

Section 12.7. Amendment. The provisions of this Agreement may be amended or waived only by an instrument in writing signed by the parties hereto.

Section 12.8. Maximum Interest Rate. No provision of this Agreement or of any other Loan Documents shall require the payment or the collection of interest in excess of the Maximum Rate. If any excess of interest in such respect is hereby provided for, or shall be adjudicated to be so provided, in any other Loan Documents or otherwise in connection with this loan transaction, the provisions of this Section shall govern and prevail and neither Borrower nor the sureties, guarantors, successors or assigns of Borrower shall be obligated to pay the excess amount of such interest or any other excess sum paid for the use, forbearance or detention of sums loaned pursuant hereto. In the event Lender ever receives, collects or applies as interest any such sum, such amount which would be in excess of the maximum amount permitted by applicable law shall be applied as a payment and reduction of the principal of the indebtedness evidenced by the Notes; and, if the principal of the Notes have been paid in full, any remaining excess shall forthwith be paid to Borrower. In determining whether or not the interest paid or payable exceeds the Maximum Rate, Borrower and Lender shall, to the extent permitted by applicable law, (a) characterize any non-principal payment as an expense, fee or premium rather than as interest, (b) exclude voluntary prepayments and the effects thereof and (c) amortize, prorate, allocate and spread in equal or unequal parts the total amount of interest throughout the

entire contemplated term of the indebtedness evidenced by the Notes so that interest for the entire term does not exceed the Maximum Rate.

Section 12.15. Consent to Participations. Lender shall have the right at any time and from time to time to sell or transfer one or more participation interests in the Notes and the indebtedness evidenced thereby to one or more purchasers (“Purchasers”), whether related or unrelated to Lender. Lender may provide to any one or more Purchasers or potential Purchasers any information, financial statements, data or knowledge Lender may have about Borrower or about any other matter relating to the Obligations, and Borrower waives any rights to privacy it may have with respect to such matters. Borrower further waives any and all notices of sale of participation interests and notices of repurchases of participation interests. Borrower agrees that the owners of any participation interests will be considered as the absolute owners of their interests in the Obligations and will have all the rights granted under the participation agreements or other agreements governing the sale of their participation interests. Borrower waives all rights of offset or counterclaim that it may now or later have against Lender or against any Purchaser and agrees that either Lender or any Purchaser may enforce Borrower’s obligations under the Loan Documents irrespective of the failure or insolvency of any owner of any interest in the Obligations. Borrower further agrees that any Purchaser may enforce its interests irrespective of any claims or defenses that Borrower may have against Lender. Lender and Purchaser(s) acknowledge that such information may include material non-public information and shall not act on or disclose any such information contrary to the rules and regulations of the Securities and Exchange Commission.
